Niles: Oh, what about this one? Frasier, you really must make a decision. We've been to six stores already, and oh, that reminds me, I must cancel our squash game tomorrow...
Frasier: Don't you hear that?
Niles: Yes, now that you mention it, I do. It's sort of like a nervous tic of some kind. I wonder what could be causing it.
Frasier: Well, let's see: you do have a baby on the way. Perhaps your incessant jabbering is just a way of distracting yourself from this life changing event.
Niles: How could I have missed something so obvious?
Frasier: Well, it's not so hard to believe. You were fifteen before you discovered there was a correlation between being beaten up every day and going to school in a Panama hat.
